WADL Aircraft Segment Installation Description

Transcription

1 To: From: Bay Area Compliance Lab Corporation Jason Funderburk, Date: /2/200 Re: WADL Aircraft Segment Installation Description I lieu of an Installation or Users Manual this document will describe the installation of the Aircraft Segment of the Wireless Aircraft Data Link (WADL) system manufactured and installed on commercial aircraft by. The WADL Aircraft segment is to be tested by BACL for compliance under FCC Part 1C. The WADL Aircraft Segment is certified by the FAA for installation on Airbus A-20 and A-19 aircraft. Currently held certifications are: A-20 Supplemental Type Certification ST01NY Granted: 11 February 2002 A-19 Supplemental Type Certification ST00SE Last Amended: December 2002 During the installation process all physical installation steps, inspections, and checkout procedures are documented on generated Work Orders. An example set of work orders for the A-19 are shown in an attachment to this document. The installation and certification processes are described in general in the sections below. Statement of Professional Installation and Certification Aircraft Segment Statement: The WADL Aircraft Segment must be professionally installed because each installation is custom suited to meet the demands of the specific environment. The FAA requires a Supplemental Type Certificate (STC) for any changes to an existing aircraft type. When an airline acquires WADL Aircraft Segments for installation in a specific aircraft type, the airline s aircraft engineering personnel meet with engineers to jointly develop an installation drawing package. A tray location is identified and selected from available options in the avionics equipment bay. The best way to get power to the tray is determined and a circuit breaker is assigned in the flight deck. Interfaces to other avionics equipment and aircraft discretes are similarly identified and installed. All new wiring must comply with strict federal regulations and standards for installation. A location for the aircraft antenna is chosen on the top side of the aircraft taking into account availability, accessibility, electromagnetic compatibility, and aerodynamic efficiency. Once defined, new drawings are created that define how the aircraft skin is penetrated and a doubler plate installed for antenna mounting, structural support, and environmental sealing. A nearby location for the LNA/PA is chosen between the passenger cabin and the aircraft skin. The closest stanchion is identified and the method of mounting the LNA/PA is documented. The RF Cable is then pulled through the aircraft to its destination. The cable is routed and restrained in compliance with specified installation standards. The cable is cut to length and terminated at both ends. The power level at the input to the RF Assembly is checked to make sure that it is within the input dynamic range of the amplifier. All details of the modification are carefully documented and inspected by the FAA. 1

2 The installation is verified by using an installation test set to verify functionality. A variety of ground tests are performed to assess the electromagnetic compatibility of the newly installed equipment with existing flight critical equipment. An STC Aircraft Test is then performed to verify the electromagnetic compatibility of the newly installed equipment with existing flight critical equipment. At the conclusion, an STC package consisting of the drawing package and test data is prepared. The STC package is then submitted for review by the FAA. Upon their approval, an STC for the defined type of aircraft is granted. Once granted, the STC is only valid for that specific aircraft type. If the airline desires to install the WADL Aircraft Segment in another type of aircraft, the process is repeated. All aircraft of a specific type are modified in exactly the same fashion based on the STC drawing package. Installations are carefully inspected and discrepancies are documented and properly corrected. The installation and controls process are such that the system will always be configured as per the installation design. The FAA certification requires that all cables and system pieces be in place per installation drawing, else the aircraft is not allowed to fly. The air transport industry carefully controls the configuration of installed avionics equipment. The FAA issues a Supplemental Type Certificate for the aircraft on the basis of the newly installed, tested, and approved equipment. Any changes to the installation or hardware baseline would require their approval. has and will continue to state that tampering with or modifying installed equipment could result in damage to the installed equipment and a violation of FCC regulations. Conclusion: Taken as a whole the STC process, professional installation per documented Work Orders, and strict FAA regulations with respect to aircraft maintenance and configuration will insure that the system as installed and maintained will remain compliant as defined in FCC Part 1C and verified by the TCB. 2
